MOT2

NOT4, SIG1, CCR4-NOT core ubiquitin-protein ligase subunit MOT2, L000001887, L000001137, YER068W
Ubiquitin-protein ligase subunit of the CCR4-NOT complex; with Ubc4p, ubiquitinates nascent polypeptide-associated complex subunits and histone demethyase Jhd2p; CCR4-NOT has roles in transcription regulation, mRNA degradation, and post-transcriptional modifications; regulates levels of DNA Polymerase-{alpha} to promote efficient and accurate DNA replication

YKE2

GIM1, PFD6, L000002791, YLR200W
Subunit of the heterohexameric Gim/prefoldin protein complex; involved in the folding of alpha-tubulin, beta-tubulin, and actin; prefoldin complex also localizes to chromatin of actively transcribed genes in the nucleus and facilitates transcriptional elongation

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Modulation of Ubc4p/Ubc5p-mediated stress responses by the RING-finger-dependent ubiquitin-protein ligase Not4p in Saccharomyces cerevisiae.

Mulder KW, Inagaki A, Cameroni E, Mousson F, Winkler GS, De Virgilio C, Collart MA, Timmers HT

The Ccr4-Not complex consists of nine subunits and acts as a regulator of mRNA biogenesis in Saccharomyces cerevisiae. The human ortholog of yeast NOT4, CNOT4, displays UbcH5B-dependent ubiquitin-protein ligase (E3 ligase) activity in a reconstituted in vitro system. However, an in vivo role for this enzymatic activity has not been identified. Site-directed mutagenesis of the RING finger of yeast Not4p ... [more]
